Clinical Profile and Out Come of Pregnancies with NRFHR in Labor at Three Teaching Hospitals, Addis Ababa, Ethiopia
ABSTRACTBackground: Intrapartum fetal heart rate monitoring with intermittent auscultation using fetoscope is still the method in use in Ethiopia and other developing countries. The purpose of this study was to evaluate the prevalence of NRFHR using intermittent auscultation and related operative intervention rates, perinatal out comes and factors associated.Methodology: This is a cross-sectional study. Data was collected using pre-tested questionnaire June-September, 2005 at 3 teaching hospitals in Addis Ababa, Ethiopia. All laboring women with alive fetus at admission to the labor ward and developed NRFHR while followed with intermittent auscultation were included. Result: There were 257 deliveries with NRFHR out of a total of 1379 deliveries during the study period. Prevalence of NRFHR in labor was 18.6% (257/1379). Bradycardia was the commonest FHR abnormality (65%). Cesarean section was the mode of delivery in 43% of cases with NRFHR and cesarean section rate for NRFHR was 7.5%. The positive predictive value of intermittent auscultation for low 1st and 5th minutes APGAR scores were 38.9% & 13.2% respectively. Low apgar score (LAS) rate was higher in those with no ANC follow-up (37.5% Vs 8.9%), address outside Addis Ababa (27.5% Vs 10.6%), referred in labor from other hospitals Vs health centers (23.8% Vs 8.9%), thickly meconium stained liquor Vs clear liquor (38.1% Vs 3.0%) and decision-delivery interval in cesarean section of >30 mins (18.6% Vs 3.8% ).Conclusions & recommendations: The prevalence of NRFHR and cesarean delivery rate for NRFHR are high compared to previous similar studies done locally and in other countries. The quality of intrapartum fetal monitoring needs to be improved and other supplementary tests or monitoring techniques, like selective use of EFM should be considered.
